MECHANISM FOR LOCKING CAR-DOORS.

Application filed June 12, 191 1.

mechanism for locking and sealing car doors, and its aim is to provide a mechanism including a sliding wedge to be dropped in the path of a flange or tongue at one end of the door for locking the same, there being a hasp lever to engage an apertured lug at the other end of the door for further locking the same. Both locking mechanisms include means for sealing the same.

In practical fields the details of construction may necessitate alterations, falling within the scope of what is claimed.

The invention comprises further features and combination of parts, as hereinafter set forth, shown in the drawings and claimed.

In the drawings:Figure 1 is a View in side elevation showing the door unlocked and open. Fig. 2 is a side elevation showing the door closed, locked and sealed. Fig. 3 is a sectional view on line 3-3 of Fig. 2, showing the vertical trough-shaped bar with the sliding wedge therein. Fig. 4 is a sectional view on line 4.4 of Fig. 2 showing the wedge in the path of a flange upon the door. Fig. 5 is a detail perspective view of the locking wedge and its attending parts for locking one end of the door.

As to the drawings, 1 designates a portion of a car body provided with the usual door opening 2. Extending partially of the length of the car body and disposed in close position to the upper edge of the door opening is a supporting member, on which the door 5 is hung in place, so as to slide to an open or closed position. The lower edge of the door is guided and held in place by suitable guides.

Secured at 14: above the hanger rail 10 is a bracket 15, while below the lower edge of the door 5 is a second bracket 16 secured at 17. Bolted or otherwise secured to said brackets 15 and 16 is a trough-shaped guide bar 18 having a slot 19. The bracket 15 extends outwardly farther than the bracket Specification of Letters Patent.

16, so as to hold the bar 18 at an angle relative to thedoor 5. Upon the outerface of the door adjacent the edge 20 thereof and secured at 21 is a wear plate 22 having a flange Mounted in the trouglrshaped bar 18 is a wedge 24-, designed to engage the i wear plate 22, wedging between the same and the bar 18 when the wedge is down, thereby holding the door closely in contact with the side of the car body, while the plate 4 is of a resilient character actingto hold the opposite edge of the door closely in contact with the car body. The wedge 24- is provided with a tongue 25 extending through the slot 19, said tongue being provided with lateral lugs 27 to hold the wedge in the trough-shaped bar. The lugs 27 engage upon the outer surface of the bar 18.3

\Vhen the wedge is down as shown inFi 2, it engages the wear plate 22 in the path of the flange 23, so as to prevent the door 5 from being opened. Secured at 28 to the bar 18 is a section of chain 29 having a loop 30 which fits over the tongue 25, which is provided with an aperture 31, which receives the usual sealing device 32. Said chain is of such a length as to prevent the wedge from being moved upwardly, that is, when the sealing device is attached. However, when the seal is broken, the loop of said chain may be removed from the tongue, and. by grasping and pushing upwardly upon the tongue, the wedge may be disposed above the upper end of the flange 23, and held in suchposition by the latch plate 34, which. is thrown in the path of the tongue, as shown in Fig. 1. Said latch plate 34 is hinged to the bar 18 as shown at 35. "When the wedge is held upwardly above said flange 23. the door 5 may be opened, that is, when the other end or opposite edge of the door is unlocked and unsealed.

The invention having been set forth,what is claimed as new and useful is:--

1. In combination, a car body having a door opening, a door therefor, a pair of brackets, one above and one below the door, a trough-shaped guide bar connecting said brackets and arranged at an angle to the door, a wear plate having a lateral flange secured adiacent one edge of the door, a wedge slidably mounted in said troughshaped bar and adapted to wedge between the wear plate and the bar and in the path of said flange, and means for locking and sealing said wedge in such position.

2. In combination, a car body having a door opening, a door therefor, a pair of brackets, one above and one below the door, a trough-shaped guide bar connecting said brackets and arranged at an angle to the door, a wear plate having a lateral flange secured adjacent one edge of the door,a wedge slidably mounted in said tr0ughshaped bar and adapted to wedge between the wear plate and the bar and in the'path ofsaid flange, and means for locking and sealing said wedge in such position, and means for holding the wedge in a raised position out of the path of said flange.

'3. In combination with a car body having a door opening, a door therefor, atroughshaped guide bar secured adjacent the door and arranged at an angle relative thereto and provided with an elongated slot, a wear plate secured to the door adjacent one edge Copies of this patent may be obtained for thereof and provided with a flange and adapted to assume a position behind the trough-shaped bar when the door is closed, a wedge slidably arranged in the troughshaped bar adapted to wedge between the same and the wear plate and provided with a tongue passing through the slot, said tongue having lateral lugs to hold the tongue and wedge in place, and sealing means connecting the tongue and the trough-shaped bar to prevent the wedge from being raised.

In testimony whereof I :have signed my name to this specification in the "presence of two subscribing witnesses.
